AND IT IS not conceivable that a believer should slay another believer, unless it be by mistake. And upon him who has slain a believer by mistake there is the duty of freeing a believing soul from bondage and paying an indemnity to the victim's relations, unless they forgo it by way of charity. Now if the slain, while himself a believer, belonged to a people who are at war with you, [the penance shall be confined to] the freeing of a believing soul from bondage; whereas, if he belonged to a people to whom you are bound by a covenant, [it shall consist of] an indemnity to be paid to his relations in addition to the freeing of a believing soul from bondage. And he who does not have the wherewithal shall fast [instead] for two consecutive months. [This is] the atonement ordained by God: and God is indeed all-knowing, wise. 92 And whoso slays a believer wilfully, his recompense is Gehenna, therein dwelling forever, and God will be wroth with him and will curse him, and prepare for him a mighty chastisement. 93 O you who have believed, when you go forth [to fight] in the cause of Allah, investigate; and do not say to one who gives you [a greeting of] peace "You are not a believer," aspiring for the goods of worldly life; for with Allah are many acquisitions. You [yourselves] were like that before; then Allah conferred His favor upon you, so investigate. Indeed Allah is ever, with what you do, Acquainted. 94 Those believers who stay behind, apart from those forced by necessity, are not equal to those who strive hard in God's cause with their possessions and their persons. God has given those who strive with their goods and their persons a higher rank than those who stayed behind. God has promised all a good reward; but far greater is the recompense of those who strive for Him -- 95 high ranks conferred by Him as well as forgiveness and mercy. God is forgiving and merciful. 96
